Abstract
In the case of a medical device with several electronic components, a possibility must be provided for enabling the components to be rapidly matched to each other, in order to guarantee the functional correctness of the medical device. In particular in the case when, for example, an item of operating software is modified for one individual component only, it can occur that this component no longer interoperates with the other components in a desired way. In this context, at a particular point in time, for each of the electronic components of a apparatus data for the component is copied and the copied data is stored outside the storage facility of the component, making it possible at a later point in time, which can be defined, for the copied data for each component to be stored in its storage facility.
Description
- This application claims priority of German application No. 10 2009 014 621.0 filed Mar. 24, 2009, which is incorporated by reference herein in its entirety.
- The invention relates to a method for operating an apparatus with electronic components, in particular of a medical device, a method for integrating an electronic component into such an apparatus, and to a medical device with a communication facility, a central storage device and at least one further electronic component in accordance with the claims.
- Large medical devices for investigating or operating on patients may incorporate several computers, microprocessors or control units which, within the medical device, monitor and control individual parts of the medical device. By means of a communication network inside the device, these individual electronic components of the medical device can exchange items of data, by which means the components enhance each other's functionality. An example of such a complex medical device is the applicant company's Artis Zee multi-purpose system.
- During the operation of such a medical device, it is consistently necessary to carry out maintenance work on the individual components. For example, it can happen that the manufacturer of a control unit built into the medical device makes available an improved version of a control program, or that a program for a computer which is built into the medical device is replaced by a version of it which has been further developed.
- Such maintenance can also change such functions of a component which are used by another component of the medical device. Thus, for example, a computer makes available items of control data which are called up by a control unit and, for example, used to control an x-ray unit in the medical device.
- When making a change to such functions of a component, which are used by other components, it is always necessary to avoid a component being no longer able, after a maintenance action, to receive items of data from another component, because it is unable to call up the data appropriately to the other component's new mode of operation. It is equally essential to avoid the interoperation between the components being disrupted after maintenance work, e.g. by an incorrectly installed program.
- Malfunctions which arise in conjunction with an incompatible or faulty mode of operation by individual components in a medical device would, namely, very probably only become apparent when a component of the medical device wishes to use the doubtful function. However, at this point in time it would then be difficult and time-consuming to find out exactly which function is causing the malfunction. Also, it would then often no longer be clear which component must be adjusted in order to eliminate the malfunction, without in doing so causing malfunctions in other places.
- Similar problems arise for a medical device if a component is defective and must be replaced by a new component. It is then very time-consuming to match the new component to the other components in the medical device in such a way that the medical device as a whole returns to fault-free functioning.
- The down times of the medical device arising in conjunction with fault location and the mutual rematching of the components of a medical device are unacceptable. Due to the high procurement cost, such a device is often planned for investigations or operations around the clock. It may also be that such a device must, for example, be constantly available for emergencies.
- In relation to a reconstruction of data which has been deleted from a storage facility in a computer against the user's wishes, the known method is to store a copy of important data items from the storage facility at regular intervals in a second storage facility, where they are protected against any intervention by the user. Such a copy is also referred to as a backup of the data. If needed, the copied data can then be made available to the user. This procedure is also called a restore or reconstruction.
- The object of the present invention is to create the possibility, for an apparatus, in particular a medical device with several electronic components, of being able rapidly to match a plurality of the components to each other in such a way that the functional integrity of the apparatus is guaranteed.
- This object is achieved by a method of operating an apparatus, by a method for integrating an electronic component, and by a medical device as claimed in the claims.
- With the method in accordance with the invention for operating an apparatus, it is possible to operate an apparatus in which at least two electronic components interoperate, and a method of working for each component which determines the interoperation is defined by data items which are stored in a storage facility of the component in each instance. The apparatus is preferably a medical device. If the electronic component in this case is a computer, the data items might then be, for example, the operating software and configuration data on the computer's hard disk. However, the data items might also be parameter values for a configurable control unit, e.g. for a digital x-ray device or a positionable patient table.
- In accordance with the method, when a particular configuration state exists for the apparatus, the data for a component is copied for each of the components and the copied data is stored outside the component's storage facility, thus making it possible at a definable later point in time to store the copied data items for each component into the storage facility. Here, a configuration state of the apparatus is determined by the totality of the data items which are stored in the components' storage facilities and by which the ways of working of the individual components are defined. Overall, the mode of operation of the apparatus itself is also defined by the totality of the data items. Correspondingly, the configuration state is modified by storing new data, e.g. new software or new parameter values, in at least one storage facility of one of the electronic components.
- This method in accordance with the invention gives the advantage that the apparatus can at any time be put into a state in which the apparatus has already been once before and in which the components function in a desired way. For this purpose, according to the method a point in time is first determined at which the apparatus is in a desired state. At this point in time, the data items are then read out from all the components, and saved. Indirectly, therefore, the state of the apparatus itself is thereby recorded. This state can be restored by writing the saved data back into the storage units of the individual components of the apparatus.
- Here, the copying of the data items need not take place at exactly the one and same time. The copying of the data can take place over a time interval during which the apparatus is unchanged in the particular configuration state which is to be made restorable by the copying of the data items and the storage of the copied data items.
- An advantageous development of the method is given by the following additional steps:
- detect an operating state of the apparatus,
- depending on the operating state which has been detected, if necessary interrupt the interoperation of all the components and for each component store the copied data items in the storage facility.
- By this development of the method it is possible to achieve the effect that the apparatus functions once more in an acceptable way after the apparatus had got into an undesired operating state. The detection of the operating state will preferably take place automatically.
- However, it is very difficult in the case of a complex system, consisting for example of several computers, to automatically detect an operating state of the device. Here, an advantageous development of the method results if the actuation of an operating element effects for all the components the storage of the copied data items in the storage facility. By this means, an operator is afforded in an advantageous way a possibility for manually restoring a state of the apparatus represented by the copied data items.
- A further advantageous development of the method results if the copied data items for the components are stored externally in a common central store. This central store makes available in an advantageous way a facility in which are stored all those items of data which are necessary for putting the apparatus into a particular state.
- The method is, furthermore, developed in an advantageous way if a memory map of a storage medium in the storage facility is created for the purpose of copying the items of data. Preferably, the storage facility concerned will be a hard disk. A corresponding memory map is then referred to as a “disk image” (hard disk storage map or hard disk map). This development of the method gives the advantage that it is possible to copy the data items independently of the structure in which the data items are held on the storage medium. Apart from this, it is advantageous that the data items can be written back even if the storage medium has not yet been prepared, for example by formatting, for having data written to it.
- A further advantageous development of the method results if the way in which the components work can be defined in addition by conveying to the components instructional data, via a communication network, and in order for each component to effect storage of the copied data in the storage facility instructional data is initially conveyed to the component, defining the mode of operation of the component in such a way that the component stores the copied data in its storage facility.
- This gives the advantage that the writing back of the copied data items into the individual components' storage units can be controlled centrally. For example, a component with which the apparatus is provided might be a central control unit which, if a fault occurs, conveys the instructional data to the other components and then prompts the components prepared in this way to call up the copied data from a central store and to store it in the storage facility of the component concerned.
- A further advantage results when the data items or the instructional data include program codes. This makes it advantageously possible also to use the method for any apparatuses in which a computer network comprising several computers is a component of the apparatus.
- Finally, the method is advantageously developed in that the step which includes the copying of the data and the storage of the copied data is
- a) repeated at prescribed points in time, or
- b) carried out after or before a change, in particular each change, is made to data in at least one of the storage facilities.
- In that the state of the apparatus is, in accordance with sub-step a), regularly detected and saved, and indeed preferably automatically, data items will be saved while the apparatus is in different states. Preferably, several sets of detected data will be stored, where a set of detected data includes the data items detected at a particular point in time. If a malfunction of the apparatus occurs the different sets of recorded data then advantageously make available a choice of states into which the apparatus can be put. Automatic saving of the data items achieves the additional effect that the saving of the data does not require an operator to initiate it. Sub-step b) gives the advantage that any change to the data in the components' storage facilities can be reversed at any time.
- A solution to the object is also given by a method in accordance with the invention for integrating an electronic component into a medical device. This method can be used for an electronic component for which a method of working can be defined by data where the data is stored in a storage facility for the component. Here again, an example of such a component is a computer, on which software can be stored on the hard disk as the storage facility. The method includes the steps:
- linking the component to the medical device,
- transmitting the data from a central store on the medical device to the component and store the data in the component's storage facility.
- This method in accordance with the invention gives the advantage that a new component can be matched to the other components of the apparatus in a simple way.
- The method is developed in an advantageous way in that the data is copied from another electronic component's storage facility and is stored in the central store, and the other component is removed and replaced by the component which is to be integrated into the device.
- In an advantageous way, the new component of the apparatus which is to be integrated thereby automatically provides those functions which were made available by the other components before its removal. In other words, the effort involved when a defective component is replaced by a new component can be reduced.
- This is especially advantageous when the data includes program codes. It even permits a computer in a system to be exchanged without the new computer needing to be equipped in some special way with software for operation within the apparatus.
- The other developments, described in connection with the inventive method for operating an apparatus, are of course also transferable in an appropriate way to the inventive method for integrating an electronic component. Correspondingly, the advantages described in connection with the development concerned, of the method for operating an apparatus, also apply.
- The invention also covers a medical device with a control unit, a communication facility, a central storage device and at least one other electronic component. In the case of the device in accordance with the invention, a mode of operation of the component can also be defined by data if this data is stored in a storage facility for the component. In addition, the component is linked to the communication facility via one of several connections. In addition, data to define different modes of operation of a component are stored in the device, in the central storage device.

FIG. 2 the plan as shown inFIG. 1 highlighting operations, which take place in the integration of a new computer into the multi-purpose system, in accordance with one form of embodiment of the inventive method for integrating an electronic component into the multi-purpose system. - The exemplary embodiments represent preferred forms of embodiment of the invention.
-
FIG. 1 illustrates a plan for a medicalmulti-purpose system 10, whereseveral computers multi-purpose system 10. In themulti-purpose system 10, thecomputers common network facility 20 of themulti-purpose system 10. In the present case thenetwork facility 20 conforms to the Ethernet standard. - In the example shown in
FIG. 1 , thecomputer 12 provides a central control system for themulti-purpose system 10. An operating state, for example, of themulti-purpose system 10 can be indicated to an operator via thecomputer 12. Apart from this, provision can be made that the operator effects settings for themulti-purpose system 10 via thecomputer 12. In doing so, control instructions are conveyed from thecomputer 12 to theother computers computers computer 12. - The
computer 14 is used to control an x-ray C-arm, not shown inFIG. 1 , of themulti-purpose system 10, through which the digital medical image data can be obtained. This is then transmitted to thecomputer 16. - The image data obtained by means of the x-ray C-arm can then be observed by a user of the
multi-purpose system 10 on a screen of thecomputer 16, not shown inFIG. 1 . What cannot be seen fromFIG. 1 is that thecomputer 16 is accommodated in a different room from that in which the x-ray C-arm of themulti-purpose system 10 is standing. In spite of this, thecomputer 16 is a component of the multi-purpose system. - The
computer 18 belongs to an operating unit which is located directly adjacent to a patient table of themulti-purpose system 10, not shown inFIG. 1 . Not shown inFIG. 1 is a screen for thecomputer 18 with a touch-sensitive surface (a touchscreen), through which the user can move the patient table and the x-ray C-arm. In doing this, control instructions are transmitted from thecomputer 18 to thecomputer 14. - The structure of the multi-purpose system just described is only chosen as an example, to enable the elements which are essential for an explanation of the invention to be better visualized in what follows.
- Each of the
computers multi-purpose system 10 provides ahard disk computer individual computers hard disk computers computers other computers computers - Also connected to the
network facility 20 is acentral file server 30, e.g. an NAS (Network Attached Storage). In the file server are held files which are used by thecomputers hard disks central file server 30, it is also possible to provide for the files in thecomputer 12 to be held in a storage device which is designed for that purpose or to make available another computer with storage capacity appropriate for holding the files. - Stored on each
hard disk FIG. 1 in apartition computer relevant partition hard disk file server 30, where they are stored as ahard disk image 32′, 34′, 36′, 38′ on a hard disk array 40 (RAID—Redundant Array of Inexpensive Discs) in thefile server 30. InFIG. 1 , the procedure of transmitting thehard disk images 32′, 34′, 36′, 38′ of thepartitions file server 30 is indicated by arrows. Thehard disk images 32′, 34′, 36′, 38′ can be created using software known from the prior art, which can be a component of the software installed as on the computer concerned. - The time point at which the
computers hard disk images 32′, 34′, 36′, 38′ and transmit them to thefile server 30 can, for example, be defined in advance by an operator atcomputer 12. At the time point thus prescribed, thecomputer 12 then autonomously transmits an appropriate signal via thenetwork facility 20 to theother computers hard disk images 32′, 34′, 36′, 38′ and to transmit them to thefile server 30. The operator can also be given the option, by thecomputer 12, to initiate the creation of hard disk images by directly calling up an appropriate function of some control software on thecomputer 12. - It is also possible to store on the file server several hard disk images of each
hard disk computer 12 of the images which can be called up on thefile server 30. - The image data, for example obtained by means of an x-ray C-arm, can be called up from outside the
multi-purpose system 10 via thecomputer 12, through anetwork connection 42 of themulti-purpose system 10. For this purpose, the image data is stored in thecomputer 12 on a hard disk array (RAID), not shown inFIG. 1 . It is also possible to enable the storage of thehard disk images 32′, 34′, 36′, 38′, in a file server which is not directly connected to thenetwork facility 20, via thenetwork connection 42. - A plan of the
multi-purpose system 10 described in conjunction withFIG. 1 is shown once again inFIG. 2 . For this reason the same reference marks are used inFIG. 2 for those elements which correspond to elements shown inFIG. 1 . Furthermore, elements which have already been explained in conjunction withFIG. 1 are not explained again. - The way in which a defective computer in the
multi-purpose system 10 is replaced by a new one, and the latter is configured for operation within themulti-purpose system 10 is explained below by reference toFIG. 2 . - In the situation shown in
FIG. 2 , thecomputer 18 shown inFIG. 1 has been removed from themulti-purpose system 10 and has been replaced by anew computer 44. In this example, ahard disk 46 on thenew computer 44 contains absolutely no data. In other words, thehard disk 46 has not yet been partitioned or formatted. - After the
multi-purpose system 10 is switched on, the operating system is loaded into a working store in each of thecomputers computers new computer 44, the necessary data for doing this is missing from the unwrittenhard disk 46. For this reason, anetwork card 48 in thenew computer 44 here generates a signal conforming to a data protocol (BOOTP—Bootstrap Protocol) intended for the purpose. This signal is transmitted to thecomputer 12 which has the control system. InFIG. 2 this is indicated by an arrow for a transmission, T1. - The
computer 12 thereupon transmits, in a transmission T2, anauxiliary operating system 50 to thenew computer 44, which is then put in a position to provide simple functions by means of theauxiliary operating system 50. The program code of the auxiliary operating system here represents instructional data. - In addition, by means of an appropriate piece of server software (DHCPD—Dynamic Host Configuration Protocol Daemon), the
computer 12 assigns to the new computer 44 a network address, which is here an IP address (IP—Internet Protocol) because thenetwork facility 20 is a facility conforming to the Ethernet standard. The network address which is assigned to thenew computer 44 is determined as a function of theconnection 52 via which thenew computer 44 is linked with thenetwork facility 20. As a result, thenew computer 44 in the example is given the same network address as had previously been given to thedefective computer 18 which has been removed. Theparticular connection network facility 20, to which thenew computer 44 is connected, is notified to thecomputer 20 by a switch, not shown inFIG. 2 , in thenetwork facility 20. - The
auxiliary operating system 50 requests from thefile server 30 thehard disk image 38′ which had been stored by thecomputer 18 which was previously connected to theconnection 52. The request for the transmission of thehard disk image 38′ is identified in.FIG. 2 as the transmission T3. - The
file server 30 thereupon transmits thehard disk image 38′ to thenew computer 44, which stores thehard disk image 38′ on itshard disk 46. The transmission procedure is identified inFIG. 2 as the transmission T4. - The storage of the
hard disk image 38′ on thehard disk 46 automatically produces on the hard disk 46 a partition with a file system, and contained therein an operating system together with the additional software, as was also present on itshard disk 28 in the case of thedefective computer 18. Hence, after a restart of thenew computer 44 it makes available the same functions as did previously thecomputer 18. The integration of thenew computer 44 into themulti-purpose system 10 is thereby completed. - In the case of the
multi-purpose system 10, provision can be made for the partitions of the hard disks on all thecomputers file server 30. For this purpose, provision can be made for a user of themulti-purpose system 10 to select an appropriate function on thecomputer 12 to initiate the writing back of thehard disk images 32′, 34′, 36′, 38′ by thedata server 30 to the hard disks of the computers. In this connection, provision can be made that there is a piece of software installed on eachcomputer auxiliary operating system 50. For these auxiliary operating systems it is here possible to define in advance data about which hard disk image they should each call up from thedata server 30 and should store on the hard disk of the computer concerned. - When all the hard disks have been rewritten with the appropriate hard disk images, the
multi-purpose system 10 is restarted. Themulti-purpose system 10 is then in the operating state as defined by thehard disk images 32′, 34′, 36′, 38′. All the changes to the software of themulti-purpose system 10, which had been made in the period between the creation of thehard disk images 32′, 34′, 36′, 38′ and the writing back of these to the hard disks of the computers from which they originated, are thereby undone. In particular, in the case that a malfunction of the multi-purpose system results from one of the changes, resetting the multi-purpose system enables its functional correctness to be reestablished rapidly and with little work. - In summary, the example shows that the invention enables the computers of the multi-purpose system to be rapidly matched to each other in such a way that the functional correctness of the multi-purpose system is guaranteed.
